“…In 1964, Hirsch, Voelkel & Munson (5) demonstrated that highly active preparations of calcitonin may be obtained by the extraction of fresh porcine thyroid glands with dilute acid; however, most investigators have used a desiccated, defatted acetone powder of thyroid as a starting material (6)(7)(8)(9)(10)(11)(12). Purification has generally been ~ollowed by determining the hypocalcemic activity of the preparation in rats.…”

“…Extraction of the acetone powder of thyroid glands with dilute acid was usually followed by recovery of crude calcitonin through precipitation by salts, organic solvents, or trichloracetic acid. Preparation of substantially pure hormone has now been reported from several laboratories (9)(10)(11)(12)(13)(14). Purification of crude preparations has been accomplished chiefly by repeated gel filtrations with agents such as the Sephadexes; countercurrent distribution and preparative disc electrophoresis (9,11,14) have also been useful.…”
